Thermoregulation

Introduction

Preterm infant is susceptible to heat loss and hypothermia immediately after birth.

Etiology

high body surface area when compared to the body weight
decreased brown fat stores
thin poorly keratinized skin, little subcutaneous fat
immature temperature control
hypothermia may result in hypoglycemia, apnea and metabolic acidosis (cold stress)
